Restore Full Functionality to Your GM Vehicle
Is your 2010 Cadillac Escalade or another GM vehicle suffering from bizarre electrical issues? Flickering lights, malfunctioning power windows, intermittent door locks, or strange warnings on your dash are classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of frustrating problems. This isn’t just an annoyance; it can affect vehicle security and safety systems. This replacement Body Control Module, part number 15819552, is the definitive solution to get your vehicle back to 100%.
Case Study: A Tricky Diagnosis
A customer brought in their 2010 Escalade last month with a laundry list of complaints: the radio would turn off randomly, the driver’s side window wouldn’t go down, and the security light was always on. They had already replaced the battery and checked all the fuses. A scan showed a U0140 code (Lost Communication With Body Control Module). Instead of a costly and time-consuming trip to the dealer, we used our cloning service. We transferred the data from his faulty BCM to our replacement unit. Within a day, he had the part back, plugged it in, and every single issue was resolved. It’s a powerful fix that saves time and money.
What Makes Our Cloning Service the Best Choice?
Forget about paying for expensive dealership programming and key relearns. Our unique cloning service makes this repair straightforward. Here’s how it works: After your purchase, you’ll send us your vehicle’s original BCM. We then extract the precise data that is unique to your vehicle—including key fob information and specific options—and flash it onto this replacement module. We also apply the latest GM software updates using your VIN for optimal performance. We then ship both your original module and the ready-to-install replacement back to you. The result is a true plug-and-play solution, specifically configured for your exact vehicle.
Common Signs of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security system acting up or preventing the car from starting.
- ✔ Horn sounding at random or not working when pressed.
- ✔ Dashboard warning lights (like ABS, Airbag, or Traction Control) staying on.
- ✔ Communication error codes, such as U0140, U0155, or B1001.
A Straightforward Guide to Installation
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: On a 2010 Escalade, the BCM is typically located under the driver’s side dashboard, near the steering column. For other models, its location may vary (e.g., center dash in Express vans).
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, remove any bolts or clips holding the module in place and take it out.
- Install the New Module: Seat the new, programmed BCM in the same position and secure it with the original hardware.
- Reconnect: Firmly plug all electrical connectors into the new module. You should hear a click as they lock into place.
- Final Steps: Reconnect the negative battery terminal. Start the vehicle and test all body functions (lights, locks, windows, etc.) to confirm the repair. Note the post-installation procedures below.
Important Post-Installation Information
While our cloning service makes this repair as simple as possible, some vehicle systems may require a recalibration procedure after the new BCM is installed. This is normal. Please be aware of the following potential requirements:
- Airbag System Sync: If your airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be necessary to ensure correct brake light operation and to prevent issues with the traction control system.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What exactly does a Body Control Module do?
The BCM acts as the main computer for your vehicle’s comfort and convenience features. It controls functions that aren’t related to the engine, like power windows, locks, interior lighting, security system, wipers, and more.
Do I need to get this module programmed by a dealer?
No. Our cloning service handles all the programming for you before we ship the part. It will arrive ready to install in your vehicle, saving you a trip to the dealership and additional fees.
Why is cloning my original module necessary?
Cloning transfers your vehicle’s unique identity—like its specific options package and key fob data—to the new module. This ensures all features work correctly right after installation, which a generic VIN flash from a dealer often can’t guarantee without extra, costly procedures.
What happens to my original BCM?
Your original module is always returned to you along with the newly programmed replacement unit. We need it for the data transfer process, but we do not keep it.
Will this fix my ‘Service Theft System’ message?
A faulty BCM is a very common cause of this message. By cloning your original module’s security information, this replacement part is highly likely to resolve that specific issue.
